Re: how can get the number of consumers on a queue

[chrismfwrd <ch...@gmail.com>]

Hi,

how can I connect the DestinationSource and the DestinationStatistics?
I can get a DestinationSource object from an active ActiveMQConnection
containing information about the currently running queues/topics. But the
objects returned by e.g. getQueues() seem to not have any statistic
information attached.
I can create a new DestinationStatistics object, but it's all empty and i
haven't found a way to "connect" it to an active ActiveMQDestination.

So please, could someone outline how to get queue statistic information NOT
using JMX and NOT running an embedded broker (i.e. using connections
provided from e.g. new
ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER,ActiveMQConnection.DEFAULT_PASSWORD,
"tcp://localhost:61616")) ?

thanks a lot in advance and best regards,
christian
